Yes, all true milspec cans have gaskets for water-tight fit... However...
1) Note that all cans I have seen have a metal lip that overlaps on 2-3
sides, plus the latch, PLUS the pinned hinge.
2) IF you see to it that there is a conductive path via the top to the
can body via the hinge and/or latch(es), AND/OR add a bonding wire
between the lid and can,
...you have an effective electrical faraday cage up to the frequency
whose wave-length is smaller than the larges continuous gap between
adjacent metal surfaces at worst... AND because the on most cans the
pulse would have to turn corners or a 180 even then, still a pretty
effective shield.
You could always test it yourself. <smile>
